Not exactly sure what an 'evaporative control system' is but I'm gonna guess it's one of your cats? Especially with the bad O2 sensor, I believe those are plugged into the exhaust just after the cats (which could explain the bad reading). It might be as simple as replacing one of your catalytic converters, but a real mechanic will be able to tell you sure.
